Engine Problem Shaking

[Raver_Ace]

Hi All,

I was driving this morning when my car started to play up. It is a 96 Series II GTS-T, only mods are Zaust and HKS air filter. Basically is slowed down approaching a set of lights, then accelerated as they changed, not hard, very gentle, when the engine seemed to start vibrating or shaking. I could feel it through the peddles and gear knob and it sounded bad. i had to keep driving for a little bit and it slowly got worse. I only drove about 1km.

Any ideas what might be wrong, anyone had a similar problem. My first guess was one of the spark plugs was missing. But I really dont know much about cars.. i am learning though.

Any help would be great.

Cheers,

Ace.

is it a manual ? if u took off gently and it was in say 3rd gear at low speed then u will feel sum vibrations but not for a km. Could be a spark gone, get em checked but ir could be lots of things mate! happy hunting

[Raver_Ace]

It is a manual. It wasnt from taking off in the wrong gear. It was a constant thing.

I also got it serviced about a month ago and got the spark plugs replaced.

Cheers

it wouldnt be a miss cos missing doesnt make ur engine shake, check the cam gears for timing. Does it feel like loss of power as well ? if so maybe one of your chambers isnt even working like running 5 instead of 6 cylinders. If i were you id try and get it to a mechanic asap

Check the bolts (four or five) around the fan/fanclutch. I had a similar prob. after a service a little while ago. Turns out they didn't do the bolts up and I nearly lost the fan in the engine bay!!!

[Raver_Ace]

Yeah, it wasnt as powerful as it should have been. It didnt feel like i should have driven it either, but i had to keep going, and it kept going.

I'll look at the fan, but i dont think thats the problem.

I left the car where i pulled up so i cant check this stuff out till later tonight. but i am going to get it towed, again, to the mechanic tomorrow and get it sorted out.

I just signed up for RACV, so i'll get them to come out and look at it tomorrow for me. Gotta wait 24 hrs.

I am guessing its not a good idea to drive it to the mechanic.

Cheers again.

How much vibration is there? If its only a little vibration and you have a big exhaust, some times the exhaust can shake the car up a bit. Depends if you have a flexible exhaust connection between the dump and the cat. I know one mine there isn't a flexible connection and the car gently shakes at idle.

If its a hard vibration it could be anything? A fouled plug, a misfiring cylinder anything some thing out of balance....

yes it does. try driving a skyline on 5 cylinders - sounds like the engine is about to fall out until u really rev it (not recommended)

have a quick look over the ignition system

coil packs and spark plugs and make sure theres no loose connections. if you dont know alot of these cars then take it to a mechanic and explain what happened and say u think it might be misfiring on 1-2 cylinders

[nismoman18]

yeah missing is quite different then having it run on five cylinders man. i have a miss at idle and that does not make my engine shake vigorously, when it starts missing after redline the engine does not shake. IF a cylinder is not working of course it would shake, i shouldve reaphrased my post for less confusion

[Raver_Ace]

Thanks for your advice. I will get it towed to a mechanic today and hopefully its just something simple.

Thanks, Ace.

Hey, I drove a skyline with a faulty clutch and the whole body shook as well as the gear stick....but yeah no loss of power...

,

Hope it helps...

Fixed, Problem was dirty contacts in Ign/Fuel Circuit.

[nismoman18]

good stuff

[Guest nissimo]

may be a burnt out valve. this will do what u say. try a compression test if your spark is o.k. Otherwise get it to a mech like nismoman suggested. No nuts or bolts loose? clutch? flywheel?

good luck

[Guest nissimo]

excellent man! I was a bit late, and wrong. anyway catch ya

[MotoX]

where is your ign/fuel curcuit. i jsut degreased ym engine bay and im having the same problem.

i think its the AFM connections cause when i play with them i cna make the car run smoother or make it stall.

[Raver_Ace]

I am not sure, a mechanic (Dr_Drift) fixed it for me.

dr drift tha man...lolz
